Your selection of category has been mentioned, so
You've got a solid groove going here. It just feels incomplete. You need either another instrument, or a vocal (I see the Mansonesque nature here, and I really do dig it). Try distorted, whisper vocals, which are easy for anyone, and can be done well with even the cheapest of mics. You've got something here, so touch it up, take it back to the drawing board, and make it into a pro-sounding tune. It shouldn't take much, with what you've already got going!
Im with PANFLETIN on this one, as much as it isnt "original" grunge as it were, I like it, so please, more :3
Cool song dude but i have my doubts in the genre that doesn't sounds grunge it sounds more electronic to me but i guess you try to do a dirty grunge song haha perhaps if you put some lyrics and you remove a little bit of the distortion the music is going to sound more aggresive and much better dude ;)
Please contact me if you would like to use this in a project. We can discuss the details.
